CDC adds five states to confirmed swine-flu list

APActing Director of the Centers for Disease Control and PreventionRichard Besser discusses the outbreak of swine flu at the the CDC in Atlanta.

The U.S. has 91 confirmed cases of the swine flu in 10 states, with the latest confirmed cases in Massachusetts, Michigan, Arizona, Nevada and Indiana.

New Jersey health officials are waiting for the Centers for Disease Control and Prevention to confirm at least five probable cases.

Richard Besser, the acting chief of the Centers for Disease Control and Prevention, said thus far only five of those cases needed hospitalization, including a Mexican toddler who became the first death recorded in the U.S., in Texas.

The increase is not surprising. For days, CDC officials have said they expected to confirm more cases -- and more severe illnesses -- as they intensively hunt down this virus.
